A DELETE statement is used to remove specified records from a table. It can also be used to remove all records.

Syntax

DELETE FROM [ MEMORY ] table_name [ WHERE condition ]

table_name

The name of an existing table.

 

condition

An expression that returns a value of type boolean. Only rows for which this expression returns true will be deleted.

DELETE FROM developers WHERE name = 'Bob';
